Converting dates?
Dear R-users
I have some doubts about with converting dates...
e.g.
dates data
23/12/1975 0.8678
03/01/1976 0.8736
28/01/1976 0.765
13/03/1976 0,9654
...
I think that converting these dates can easily my plots...
is there a R function to convert these dates to
a julian dates and so plot that variables??
The help files as.POSIXlt, POSIXt and others
don't aswer my doubts...

Testing for the existence of a file.
Is there any way to do this (test for the existence of a file)
in R? In Splus (3.4) I can do
unix(paste("test -r", fnm), output = F)
where ``fnm'' is a character string giving the pathname of the file.
This returns 0 if the file exists and 256 if it doesn't.
I thought in R to do something like
system(paste("test -r", fnm), intern =T)

Hello!
I use the version 1.4.0 for Windows. I have made boxplots but only half of
the symbols (three letters each) show up on the X-axis? How t can one
change their size or orientation so that all show up? I attach the pdf file
to illustrate better the problem.

covariance of equal date values
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I need to count the covariance of two time series. Both of them contain
the dates' vector and vector of values. But the dates are not the same. It
means some dates of first ts are not in the second respectively. And I
need the covariance of same dates, of course.
Could anyone help me, please?
Thank you.

Rose diagrams in R?
I am looking for a function (or package) to plot histograms of directional
data such as wind direction. I believe these are called rose diagrams. Is
there an R script for this? If not, can it be constructed in a function
calling primitive graphic calls (lines, circles, boxes or polygons)?
The stars function is not quite right.

2 simple doubts
Hello,
I'm just start learning R/S-Plus, so I think this 2 doubts is going to
be too easy for you...
1) I couldn't discover what is the command for a concatenation of 2
variable strings.
2) For example, if I have three variable strings, and each one has the
name of a variable in a data matrix:
a<-V1
b<-V2
c<-V3
, is it possible to construct a command like this:

Defining time series objects
Hi All,
I am new to R, having used S-plus a number of years back.
I would like to set up a time series object for forecasting, with data
collected daily between 5th April 2001 and 16th September 2001.
Any help would be most appreciated as I have been unable to find any
suitable examples in the documentation.
Thanks,

Filtering data
Hello,
I am having difficulty filtering data. I am working with flow data
collected at a stream gage. For each record, I have a date and flow
value. I have filtered this data to only include days when flow values
exceed a given threshold.
Here is my problem. Within this subset of data, I often have several
consecutive days above the threshold. From this group of days, I wish to

a R question
Dear Sir,
I have been working with R for some time now and I am very happy with
it, but I have found a problem that I could not resolve. Could you
please give me some hint about how to transform POSIX time data in
seconds to string format?. (eg. 995752800 -> year-month,day,hour,min,
sec) I tryed with Sys.time(), strptime() and date() but without success.
Thank you very much in advance

Subtitle?
Hi,
Is it possible to add a subtitle that appears directly below the main
title?
I tried the "sub" parameter, but it adds sub-title to the bottom of the
plot.
Cheers,

question about scan()
Hi,
I am using the scan function to read from a file. In
general the syntax I am using is as follows:
scan("myfile", list(a = "", b="", c="", d=""), sep=",")
The file I am trying to read contains a #< in the 'd'
field. When the file is read into an object, the d
field comes as "" for that particular string.

plot question
Hi!
I want to display 2 graphs with different number of data points on the
x-axis. The code below scales them so it seems that testtwo has the
same number of data points as testone. How can I fix that? thanks.

x<-1:100;
plot(x,testone,type="l",xlab="",ylab="",main="",lty=4,axes=FALSE,ylim=c(-1.0,1.0),cex=1);
